PLEASE HELP ASAP -_- A train traveled for 1.5 hours to the first station, stopped for 30 minutes, then traveled for 4 hours to the final station where it stopped for 1 hour. The total distance traveled is a function of time.

Which graph most accurately represents this scenario?
A. A graph is shown with the x-axis labeled Time (in hours) and the y-axis labeled Total distance (in miles). The line begins at the origin and moves upward for 1.5 hours. The line then continues upward at a slow rate until 2 hours. From 2 to 6 hours, the line continues quickly upward. From 6 to 7 hours, it moves downward until it touches the x-axis

B. A graph is shown with the axis labeled Time (in hours) and the y axis labeled Total distance (in miles). A line is shown beginning at the origin. The line moves upward until 1.5 hours, then is a horizontal line until 2 hours. The line moves quickly upward again until 6 hours, and then is horizontal until 7 hours

C. A graph is shown with the axis labeled Time (in hours) and the y-axis labeled Total distance (in miles). The line begins at the y-axis where y equals 125. It is horizontal until 1.5 hours, then moves downward until 2 hours where it touches the x-axis. The line moves upward until 6 hours and then moves downward until 7 hours where it touches the x-axis

D. A graph is shown with the axis labeled Time (in hours) and the y-axis labeled Total distance (in miles). The line begins at y equals 125 and is horizontal for 1.5 hours. The line moves downward until 2 hours, then back up until 5.5 hours. The line is horizontal from 5.5 to 7 hours
